Use of Advanced Technology Structures on Boeing 757/767

The usage of advanced technology structures has been a significant part of the success of the Boeing 757/767 mid range airplanes. Extensive use of kevlar, graphite/epoxy, high purity aluminum, powder metallurgy, titanium and metal bonding has reduced the weight of some structural components as much as 28%. New technology in materials and structures have been combined with new aerodynamics, propulsions and systems which resulted in a reduction in fuel burn that is as much as 40% below many of the aircraft in commercial fleets today.
